Normally, weather moves from west to east. In the mid-latitudes, the prevailing winds are westerlies. This means storm systems generally move in from the West.

The colors we see in the sky are due to the rays of sunlight being split into colors of the spectrum as they pass through the atmosphere and ricochet off the gases, water vapor and particles. The amounts of water vapor and dust particles in the atmosphere are good indicators of weather conditions. They also determine which colors we will see in the sky.

During sunrise and sunset the sun is low in the sky, and it transmits light through the thickest part of the atmosphere. A red sky suggests an atmosphere loaded with dust and moisture particles. The shorter wavelengths, such as blue, are scattered and broken up. We see the red wavelengths. the longest in the color spectrum, are able to continue through the atmosphere.

Red sky at night, sailor’s delight.

A red sky at night means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west and good weather will follow.

Red sky in morning, sailor’s warning.

A red sunrise can mean that a high pressure system (good weather) has already passed, thus indicating that a storm system (low pressure) may be moving to the east. A morning sky that is a deep, fiery red can indicate that there is high water content in the atmosphere. So, rain could be on its way.
